SIEVE-GLOTH CLEANER.

Specification of Letters Patent.

Patented June 14, 1910.

T 0 all whom it may concern:

Be it known that I, Conoonn K. KiNsEY, a citizen of the United States of America, residing at Bucyrus, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Sieve- Cloth Cleaners, of which the following is a specification.

My invention relates to improvements in cloth cleaners and is especially adapted to be used with gyrating or universal bolting machines for cleaning flour and cereals.

My invention primarily consists in the application of rubbing felt for cleaning purposes.

A further object is to provide a holder for the rubbing felt that will maintain it in its proper relation to the cloth when mounted on the support.

Another object is to provide means of giving a rebound to the holder when it strikes the frame-work of the sieve so as to accelerate its movements in all directions.

I attain these and other objects by the mechanism illustrated in the accompanying drawings in which:

Figure 1, is a plan View of the holder. Fig. 2, is a cross-sectional side elevation of the holder, showing the rubbing felt clenched in the annular recess. Fig. 3, is a cross-sectional side elevation of the holder, showing the inner wall of the holder parallel with the outer wall, preparatory to receiving the rubbing felt. Fig. 4, is a plan view of the holder, showing the rubber felt fitted thereto with the upper surface serrated. Fig. 5, is a cross-sectional side elevation of Fig. 4. Fig. 6, shows a section of silk cloth that is used in the sieves of the bolting machines. Fig. 7, shows a section of a supporting wire sieve. Fig. 8, is a longitudinal side elevation of one sieve taken from an ordinary bolting machine, showing my cleaner interposed between the cloth and wire support.

In the drawings, 1 represents the outer wall of a cup expanded at 5, so as to contact with and clench the rubbing felt and retain it within the annular recess 4. The term rubbing felt refers to felt that is made of coarser fiber than is used in the manufacture of ordinary felt and when cut leaves the fibers extending slightly above the cut edge and adapted to penetrate the mesh of bolting cloth.

A portion of the rubbing felt extends above the upper surface of the holder as clearly shown in Figs. 2 and 8. In order to facilitate the beading or expanding of the inner wall 2, notches 6 areformed in the upper edge. A yielding means, preferably a rubber band 7, is adapted to fit the outer periphery of the holder and is used to accelerate the movement of the holder when it strikes any portion of the frame-work of the sieve.

In Figs. 4 and 5, a modification is shown, the upper or extending portion of the rubbing felt being provided with a number of notches or serrations 8, for the purpose of providing better facilities for cleaning coarse cereals or flour.

Reference numeral 9, represents a part of the silk cloth used in an ordinary bolting sieve, and 10 a part of the supporting wire mesh sieve.

In Fig. 8, I have shown my device supported by the wire 10, with the silk cloth 9 contacting with the upper surface of the rubbing felt 4. The frame-work of the sieve is represented by numerals 11 and 12. The use of rubbing felt for cleaning the bolting cloth of sieves has been found to possess many advantages over the use of carpet, soft cloth belting, canvas and other cleaners of a similar character. The carpet and belting draw moisture and the cleaning surfaces soon glaze over making a smooth surface which entirely destroys the cleaning properties. It will be apparent therefore that the cleaning process with the use of rubbing felt is performed much more efficiently and the capacity of the mill increased.

' The operation of my device is as follows: When movement is imparted to the bolting machine carrying the full complement of the sieves as shown in Fig. 8, a gyrating or irregular movement is continually imparted to the sieve-frames which is in turn transmitted to the holder which carries the rubbing felt of the cleaner. The rubbing felt or cleaner is made to move over practically all the surface of the silk cloth and the fibers of the felt intersect with the meshes of the cloth, cleaning the openings and preventing them from clogging up the meshes of the sieve and affecting the efiiciency of the sieve in cleaning the grain. When the yielding means which is fitted to the holder is thrown in contact with the sieve frame, it gives the holder a rebound thereby accelerating the movement of the cleaner as well as providing a cushion to soften the blow.

Having fully described my invention, what I claim and desire to secure by Letters Patent is 1. A bolting cloth cleaner for sieves consisting of a piece of cut rubbing felt adapted to be held with the cut surface thereof in operative position to engage said cloth.

2. A bolting cloth cleaner for sieves consisting of a piece of serrated rubbing felt adapted to be held with the serrated surface thereof in operative position to engage said cloth.

3. A bolting cloth cleaner for sieves consisting of a piece of cut rubbing felt and a cup shaped holder to hold the cut surface in contact with the bolting cloth.

4. A bolting cloth cleaner for sieves con sisting of a piece of rubbing felt held with the cut surface thereof in operative position to engage said cloth, a ring member having an annular groove formed therein adapted to hold said rubbing felt in place for the purpose described.

5. A bolting cloth cleaner for sieves con sisting of a piece of cut rubbing felt, a ring member provided with an annular groove and notches formed in the inner wall whereby the part of the wall between the notches can be expanded inwardly to clench the rubbing felt.

6. A bolting cloth sieve cleaner comprising a piece of cut rubbing felt and means to retain the cut edge thereof in operative position to engage'the mesh of the cloth.

In testimony whereof I affix my signature in presence of two witnesses.
